Function: Compact Class-D audio amplifier module designed to deliver high-quality stereo sound output from low-power DC sources such as USB or 5V adapters.

Power & Performance: Operates on 5V DC input and provides up to 3W per channel (2×3W) output power, making it efficient for small speaker systems.

Technology: Utilizes the PAM8403 Class-D amplifier chip for high-efficiency performance with minimal heat generation and low distortion (<10% THD).

Construction: Built on a high-quality PCB with pre-soldered pins and onboard components for quick integration and stable operation.

Compatibility: Works seamlessly with Arduino, Raspberry Pi, Bluetooth audio modules, MP3 decoders, and DIY speaker projects.

Applications: Ideal for portable speakers, DIY audio systems, computer speakers, and low-voltage amplifier setups.

Design: Compact and lightweight board with left and right channel outputs; optimized for battery-powered or USB-powered projects.

Ease of Use: Simple 5V power input and standard audio signal connections — no heat sink required due to Class-D efficiency.
